This is a small thermal insulated pouch, convenient for carrying. It's sized to hold a 200ml paper carton drink, or two 250ml canned drinks, plus a small ice pack. (See images 5-6) Perfect for carrying chilled pouch jellies, chocolate, etc. in the coming seasons. It's a size that easily fits in your bag. Size: Uses a 16cm zipper Height: Approximately 17cm Width: Approximately 14cm (at the bottom) Depth: Approximately 4cm The lining uses a 4-layer thermal insulation sheet. For washing, we recommend using a laundry net or hand washing. When ironing, turn the lining out and iron the outer fabric. It will be shipped via Yu-Packet Post Mini, so there may be some creases. This is handmade by an amateur, so it is not perfect, but I strive for careful sewing. Thank you for your understanding.
